# Implement the heap data structure using JavaScript

11:43

Heap is a data structure that can fundamentally change the performance of fairly common algorithms in Computer Science.

The heap data structure is called a heap because it satisfies the heap property. The heap property states, that if P is a parent node of C, then the value of node P is less than the value of node C.

In this lesson we discuss the key operations of the Heap data structure along with their performance. We then implement the data structure using TypeScript / JavaScript.
